"Our lives have been forever changed," Misha captioned the post according to Daily Mail who have seen the original post.

"We love [him] more than we ever thought possible and cannot wait to share every adventure with [him]."

Misha, who partnered with the Duchess of Sussex on her Smart Works Capsule Collection, married the US oil heir in a lavish ceremony in Rome last September.

The nuptials were attended by Meghan and Harry along with Princesses Beatrice and Eugenie, who was even spotted sitting next to the bride in a golf cart heading to one of the wedding events.

It's believed, though not confirmed, that Princess Beatrice and fiance Edoard Mapelli Mozzi got engaged during their trip to Italy for the wedding.

Misha was previously married to Prince Harry's friend Alexander Gilkes and is reportedly the mutual friend that set-up Harry and Meghan on their now infamous blind date.

So it's no surprise Misha and Mike were among the guests at the 2018 Royal Wedding at Windsor Castle and is considered one of the couple's closest friends.
